Find the mass (in kg) of kerosene filled up to the brim in a tank of dimensions 5m×2m× 1 m. (Density of kerosene is 800kg/m³)

Correct option is A

· Tank dimensions: 5m × 2m × 1m
· Density of kerosene: 800 kg/m^3
· Formula for mass:
Mass = Density × Volume
Calculate the Volume of the Tank
Volume = Length × Width × Height 
= 5 × 2 × 1
=10 m^3
Calculate the Mass of Kerosene
Mass = Density × Volume 
= 800 × 10
= 8,000 kg
